Why can t the steam engine become a modern means of transportation?

1. Steam engine.

Steam is not necessarily required to operate, any high-pressure gas can be used to operate a steam engine. Sometimes people use high-pressure gas to manipulate small models to test the feasibility of a new type.

2. The biggest advantage of the modern steam engine is that it can use almost all the fuel to convert thermal energy into mechanical energy.

Not as picky about its fuel as the internal combustion engine. In addition, if there is no steam engine, atomic energy.

It cannot be used.

Atomic reactors.

Neither directly nor directly producing electrical energy, an atomic reactor is actually just heating water, which is converted into useful work by the boiling steam engine. Steam does not necessarily need to be produced by combustion, for example, using a solar concentrator can also produce steam to propel a steam engine.

3. Sometimes people also use two smaller pistons with the same area as the largest piston to replace the largest piston, so that the engine can work in four steps and is relatively stable. This steam engine is especially important for ships at sea, because its steam can be re-entered into the boiler for heating after being continuously depressurized during the work.

Ships at sea must conserve water.

Because it may not be able to replenish water for a long time, while a steam engine on land can constantly replenish water. Until the Second World War, most merchant ships used this steam engine. All warships before 1905 also used this steam engine. The downside is that it's slightly less efficient.

In 1807, Robert Fulton was the first to successfully use a steam engine to drive a steamer. Using scientific theories, Watt gradually discovered the defects of the Tanchang steam engine.

From 1765 to 1790, he made a series of inventions, such as a separate condenser, an insulation layer outside the cylinder, oil-lubricated pistons, planetary gears, parallel motion linkage mechanisms, centrifugal governors, throttle valves, pressure gauges, etc., which increased the efficiency of the steam engine to more than three times that of the original Agitator Neucomen, and finally invented the industrial steam engine.

A steam engine is a reciprocating power machine that converts the energy of steam into mechanical work. The advent of the steam engine led to the Industrial Revolution in the 18th century. Until the beginning of the 20th century, it remained the most important prime mover in the world, and only later gradually gave way to the internal combustion engine and steam turbine.

A steam engine requires a boiler that boils water to produce high-pressure steam, which can use wood, coal, oil or gas, or even combustible garbage as a heat source. The steam expansion pushes the piston to do work.

It is inconvenient to travel long distances, only steam trains, and the conversion rate is too low.

Pollute the environment, low efficacy, high energy consumption.

The steam engine belongs to the external combustion engine, and the engine we commonly see belongs to the internal combustion engine. In the process of converting thermal energy into kinetic energy, the energy loss of the external combustion engine is much greater than that of the internal combustion engine, and the efficiency is low. Therefore, external combustion engines are rarely used in modern transportation.

Yes, steam ships, steam locomotives (steam locomotives) are all examples.

After Watt's refinement of the steam engine, it was supposed to be a steamboat: in 1806, Fulton began construction of his second steamboat in earnest. After more than a year of intense construction, a steamboat named the "Clémont" was finally built.

In 1807, the Clemmont was successfully tested on the Hudson River. It is not only more stable, but also faster. It is one-third faster than the average sailing ship.

This new steamship, which uses the watt steam engine as the main power, the propeller as the propulsion system, and the iron plate as the shipbuilding material, has opened a new era in the shipbuilding industry.
